Fun Stuff For The Holidays!

Digital FM Stereo

Transmitters

✔ Rock stable PLL synthesized

✔ Front panel digital control and display of all parameters!

✔ Professional metal case ✔ Super audio quality!

✔ 25m W and 1W models!

For nearly a decade we’ve been the leader in hobbyist FM radio transmitters. We told our engineers we wanted a new technology transmitter that would provide FM100 series quality without the advanced mixer features. They took it as a challenge and designed not one, but TWO transmitters!

The FM30 is designed using through-hole technology and components and is available only as a do-it-yourself kit with a 25m W output very similar to our FM25 series. Then the engineers redesigned their brand-new design using surface mount technology (SMT) for a very special factory assembled and tested FM35WT version with 1W output for our export only market! Both are designed around an RF tight vinyl clad metal enclosure for noise free and interference free operation. All settings are done through the front panel digital control and LCD display! All settings are stored in non-volatile memory for future use.

Both the FM30 and FM35WT operate on 13. 8 to 16VDC and include a 15VDC plug-in power supply. The stylish black metal case measures 5. 55"W x 6. 45"D x 1.5"H. (Note: After assembly of this do-it-yourself hobby kit, the user is responsible for complying with all FCC rules & regulations within the US, or any regulations of their respective governing body. FM35BWT is for export use and can only be shipped to locations outside the continental US or valid APO/FPO addresses or valid customs brokers for end delivery outside the continental US.)

Professional Synthesized

Stereo FM Transmitter

✔ Fully synthesized 88-108 MHz for no frequency drift

✔ Line level inputs and output

✔ All new design using SMT technology

Need professional quality features but can't justify the cost of a commercial FM exciter? The

FM25B is the answer!

A cut above the rest, the FM25B features a PIC microprocessor for easy frequency programming without the need for look-up tables or complicated formulas! The transmit frequency is easily set using DIP switches; no need for tuning coils or “tweaking” to work with today's “digital” receivers. Frequency drift is a thing of the past with PLL control making your signal rock solid all the time - just like commercial stations. Kit comes complete with case set, whip antenna, 120 VAC power adapter, 1/8" Stereo to RCA patch cable, easy assembly instructions, and the SMT parts are factory preassembled - you'll be on the air quick!

Tunable FM Stereo

Transmitter

✔ Tunable throughout the FM band,

88-108 MHz

✔ Settable pre-emphasis 50 or 75 μSec for worldwide operation

✔ Line level inputs with RCA connectors

The FM10C has plenty of power to cover your home, backyard, or city block. You'll be amazed at the exceptional audio quality of the FM10C. Tunes through the entire 88-108MHz band. Re-broadcast your favorite music commercial free and with the dynamic range the musician intended without all that nasty compression the big boys use to make their station sound louder than the competition. Compression produces a noticeably muddier and less dynamic sound. Runs on an internal 9VDC battery, external 5- 15VDC, or our AC125 power supply.

Hi-Res Elevation Sensor

✔ Elevation resolution to 1/3”!

✔ Pressure resolution to 0.0001kPa!

✔ 128x64 pixel graphical display!

✔ USB computer interface!

✔ Built-in Li-Ion battery!

The response to the UP24 was incredible!

Customers from professional land surveyors, meteorologists, scientists, pilots and hikers to the curious hobbyist were overwhelmed with its sensitivity and accuracy. Reading realtime elevation to a third of an inch blew their minds! We made it even better...introducing the next generation UP24B!

First, for extended field use, we designed an internal lithium ion power cell and a state of the art power management system. Now you can charge it while it’s connected to your USB connection, or use an external charger! Next we added a “MARK” feature. This allows storing a single data point reading when YOU want instead of blindly storing readings at the selected sample rate from an external switch (dry or electronic). Data is in comma delimited form for easy spreadsheet use. Then we streamlined the controls to make a more compact profile. The rotary menu navigation dial has been replaced by contactless proximity buttons for more reliable operation! Just touch your way through the menus without any dials or switches! All in a handheld device that weighs less than 4oz! Visit www.ramseykits.com for details, there’s just too much to fit here!

OBDII CarChip Pro

✔ Monitor vehicle performance to save gas!

✔ Stores up to 300 hours of trip details!

✔ Records time, date, distance, speed, events and up to 4 separate engine parameters!

✔ Records extreme acceleration and braking!

✔ Automatic accident log, records the last 20 seconds before impact!

✔ View and reset engine diagnostic trouble codes!

✔ Test for preliminary emissions status!

No comments are necessary about the cost of gas! We saw it approaching 4 bucks with disbelief. Then, in a blink of an eye, 5 bucks getting close! Now there’s limited availability in some areas. Will it ever end? Now it’s more important than ever to make sure your vehicle is in tip-top shape for the most economical performance possible.

Did you know old spark plugs can reduce fuel economy by 30%? It gets worse... a bad oxygen sensor cuts it by 40%! And that relates to a lot of extra gas and at 5 bucks a gallon, just do the math... That’s a LOT of money!

With the CarChip Pro you'll have complete access to all your vehicles diagnostic data at your fingertips! Sort miles by type (business, personal or driver), set thresholds for alarms, calculate gas mileage, log extreme acceleration and braking, speed, engine parameters, and a whole lot more! And as you know, extreme acceleration does not equal fuel economy! Find out who’s driving your vehicle like a race car...and deal with it!

The CarChip Pro is great if you have a new driver in the family. Easily monitor their performance and let them gain additional privileges with a good driving record! You have the proof!

No more taking your car in to see why your “check engine” light is on. The CarChip Pro will automatically provide the trouble codes and allow you to reset it! CarChip Pro includes storage for up to 300 hours of driving data! If you're unfortunate enough to be involved in an accident, it even records all the vehicle’s parameters for the last critical 20 seconds of operation! Includes USB cable, software and complete instructions.
